Description

Technical Field

[0001] This invention relates to the field of adhesive mixing, and more particularly to a mixing apparatus for achieving uniform mixing. Background Technology

[0002] Currently, the production process of adhesives usually requires mixing multiple components using stirring equipment to fully integrate them and form a stable finished product.

[0003] However, high-viscosity adhesives exhibit non-Newtonian fluid characteristics, resulting in poor flowability and strong adhesion. Conventional stirring blades are prone to insufficient shearing in localized areas and slow flow at the tank walls during rotation, leading to uneven mixing and agglomeration of the adhesive, making it difficult to meet the requirements of homogenized production. To address the uneven mixing of high-viscosity adhesives, some existing technologies have attempted to add multiple layers of blades to improve the mixing effect. However, these measures only enhance local fluid disturbance and have limited improvement on the uniformity of the overall flow field. When the volume of adhesive in the tank is large, its high viscosity prevents the stirring blades from achieving full power output, resulting in significant differences in flow velocity between the central and peripheral areas. This causes inconsistent mixing ratios of the adhesive at different locations and may even create dead zones in the mixing process, thus affecting the consistency of product performance. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a uniform mixing device. This device solves the problem in the above-mentioned technical solutions where the high viscosity of the mixing blades prevents them from achieving full power output, resulting in significant differences in flow velocity between the central and edge regions. This leads to inconsistent mixing ratios of the adhesive at different locations, and even the formation of mixing dead zones, thereby affecting the consistency of product performance.

A partition is fixedly connected to the inner wall of the mixing chamber.

[0006] Preferably, the outer wall of the rotating shaft is fixedly connected with a clamp, and the outer wall of the clamp matches the slot opened on the top of the support base. By setting the clamp, it is easy to adjust the position of the clamp, thereby adapting to mixing devices of different sizes.

[0007] Preferably, the top of the mixing box has a through opening, and the top of the mixing box is fixedly connected to a distribution hopper. By setting the distribution hopper, it is convenient to divide the colloid and avoid the large volume of colloid entering the mixing device at once.

[0008] Preferably, the discharge structure includes a fixed ring fixedly connected to the bottom of the partition, a toothed ring rotatably connected to the outer wall of the fixed ring, and a linkage gear fixedly connected to the outer wall of the drive shaft. The outer wall of the linkage gear meshes with the inner wall of the toothed ring. By setting the fixed ring, the toothed ring, and the linkage gear, it is convenient to drive the toothed ring through the helical blades.

[0009] Preferably, a connecting rod is fixedly connected to the bottom of the toothed ring, and a discharge plate is fixedly connected to the end of the connecting rod away from the toothed ring. By setting the linkage gear, connecting rod, and discharge plate, it is convenient to further stir and discharge the mixed colloid inside the mixing box.

[0010] Preferably, the bottom of the mixing box is provided with a discharge port, and the bottom of the mixing box is fixedly connected to a discharge hopper. By setting the discharge port and the discharge hopper, it is convenient to collect the mixed colloid.

[0011] Preferably, an arc-shaped plate is fixedly connected to the bottom outer wall of the partition, and an inclined plate is fixedly connected to the inner wall of the mixing box. By setting the arc-shaped plate and the inclined plate, it is convenient for the mixed colloid to enter the interior of the discharge hopper.

[0012] Preferably, the sealing structure includes a base plate fixedly connected to the inner wall of the mixing tank, a fixing block fixedly connected to the top of the base plate, a cylinder rotatably connected to the outer wall of the fixing block, a first connecting rod rotatably connected to the telescopic end of the cylinder, a second connecting rod rotatably connected to the end of the first connecting rod away from the cylinder, and a top plate rotatably connected to the end of the first connecting rod near the cylinder. The top of the fixing block abuts against the bottom of the top plate. By setting up the base plate, top plate, fixing block, cylinder, first connecting rod, and second connecting rod, it is convenient for the top plate to abut and press against the inclined plate, and for the outer wall of the inclined plate to abut against the bottom of the arc plate.

[0014] In summary, by using the mixing box, motor, drive gear, support base, rotating shaft, driven gear, telescopic rod, first bevel gear, second bevel gear, drive shaft, spiral blade, and partition in combination, the volume of glue entering the mixing box is reduced, thereby breaking the flow dead zone of high viscosity glue during the mixing process and reducing batch-to-batch quality differences caused by fluctuations in filling amount.

[0015] The use of the support base, rotating shaft, clamp, and telescopic rod allows for easy adjustment of the telescopic rod's length during use by coordinating the support base and clamp, thereby adjusting the positions of the first and second bevel gears and enabling the device to adapt to various sizes of mixing equipment.

[0016] The use of cylinders, first connecting rods, second connecting rods, return springs, support rods, and extension rods facilitates the sealing of the gap between the arc plate and the mixing box during the mixing process, preventing unmixed colloids from escaping the mixing area and thus avoiding inconsistent colloid quality.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, a mixing device for uniform mixing includes a support 1, and a mixing structure 2 is provided on the inner side wall of the support 1. The internal structure of the hybrid structure 2 is equipped with a discharge structure 3; The mixing structure 2 includes a mixing box 200 fixedly connected to the inner wall of the support 1. A motor 201 is fixedly connected to the top of the mixing box 200. The motor 201 is connected to an external power supply. A drive gear 202 is fixedly connected to the output end of the motor 201. The drive gear 202 is located at the center of the top of the mixing box 200, and the bottom of the drive gear 202 is rotatably connected to the top of the mixing box 200. A support base 203 is fixedly connected to the top of the mixing box 200. Four support bases 203 are provided, and the four support bases 203 are arranged in a circle. The gears are arranged in an array around the support base 203. Taking one support base 203 as an example, a rotating shaft 204 is rotatably connected to the inner wall of the support base 203. The rotating shaft 204 is horizontally distributed, and a driven gear 205 is fixedly connected to one end of the rotating shaft 204. The outer wall of the driven gear 205 meshes with the driving gear 202. A first bevel gear 207 is rotatably connected to the top of the mixing box 200. The first bevel gear 207 is horizontally distributed, and the axis of the driven gear 205 is aligned with the axis of the first bevel gear 207. Located on the same vertical plane, a telescopic rod 206 is fixedly connected to the end of the first bevel gear 207 near the rotating shaft 204, and the end of the telescopic rod 206 away from the first bevel gear 207 is fixedly connected to the end of the rotating shaft 204. A second bevel gear 208 is rotatably connected to the top of the mixing box 200. When the driven gear 205 rotates, it will drive the rotating shaft 204 to rotate synchronously, and will also drive the telescopic rod 206 to drive the first bevel gear 207 to rotate. Since the first bevel gear 207 and the second bevel gear 208 mesh, the first bevel gear... When wheel 207 rotates, it will synchronously drive the second bevel gear 208 to rotate. The second bevel gear 208 meshes with the first bevel gear 207. The bottom of the second bevel gear 208 is fixedly connected to a drive shaft 209. The drive shaft 209 is located inside the mixing box 200. The outer wall of the drive shaft 209 is fixedly connected to a spiral blade 210. The spiral blade 210 is arranged along the axial direction of the drive shaft 209. The inner wall of the mixing box 200 is fixedly connected to a partition 212. The partition 212 divides the internal space of the mixing box 200 into four parts. In use, the colloid is injected into the mixing chamber 200. When the colloid enters the mixing chamber 200, the motor 201 is started, which drives the drive gear 202 to rotate. At the same time, the drive gear 202 drives the driven gear 205 to rotate synchronously, thereby driving the rotating shaft 204 to rotate. This will drive the telescopic rod 206 to drive the first bevel gear 207 to rotate. Since the first bevel gear 207 meshes with the second bevel gear 208, the rotation of the first bevel gear 207 will drive the second bevel gear 208 to rotate. In turn, the second bevel gear 208 drives the drive shaft 209 to rotate, and the drive shaft 209 drives the spiral blade 210 to rotate, thus mixing the colloid located in this space.

[0022] like Figure 4 As shown, a clamp 213 is fixedly connected to the outer wall of the rotating shaft 204. Several clamps 213 are arranged in a linear array on the outer wall of the rotating shaft 204. The top of the support base 203 has a slot. The outer wall of the clamp 213 matches the slot on the top of the support base 203. In use, the operator can adjust the position of the rotating shaft 204 according to the radial dimension of the drive gear 202. When the radial dimension of the drive gear 202 is small, the operator can move the driven gear 205 away from the support base 203. The rotating shaft 204 is further engaged by the support base 203 and the clamp 213. When the driven gear 205 moves away from the support base 203, it will pull the telescopic rod 206 to extend, thereby transmitting power.

[0023] like Figure 1 As shown, the top of the mixing box 200 has four openings, which are located above the four spaces separated by the partition 212. The top of the mixing box 200 is fixedly connected to the distribution hopper 214, and the bottom of the distribution hopper 214 is provided with four diversion pipes. When the operator fills the colloid into the interior of the distribution hopper 214, the colloid is injected into the four spaces inside the mixing box 200 along the pipes at the bottom of the distribution hopper 214, thereby diverting and mixing the same batch of colloid to avoid the colloid mixing volume being too large.

[0024] like Figure 5 , Figure 8 , Figure 9As shown, the discharge structure 3 includes a fixed ring 301 fixedly connected to the bottom of the partition 212. A gear ring 302 is rotatably connected to the outer wall of the fixed ring 301. A linkage gear 303 is fixedly connected to the outer wall of the drive shaft 209. The outer wall of the linkage gear 303 meshes with the inner wall of the gear ring 302. A connecting rod 304 is fixedly connected to the bottom of the gear ring 302. A discharge plate 305 is fixedly connected to the end of the connecting rod 304 away from the gear ring 302. In use, the drive shaft 209 drives the linkage gear 303 to rotate, thereby driving the discharge plate 305 to rotate. Gear 303 drives gear ring 302 to rotate along the outer wall of fixed ring 301. At this time, gear ring 302 drives discharge plate 305 to rotate synchronously through connecting rod 304. Discharge plate 305 is located at the bottom of mixing box 200 and is in contact with the bottom of mixing box 200. When gear ring 302 rotates, it drives discharge plate 305 to rotate synchronously, thereby pushing the mixed glue at the bottom of mixing box 200, so that the glue is further mixed at the bottom of mixing box 200 and discharged by the push of driven gear 205.

[0025] like Figure 2 , Figure 5 As shown, a discharge port 306 is provided through the bottom of the mixing box 200, and a discharge hopper 308 is fixedly connected to the bottom of the mixing box 200. When the driven gear 205 rotates to push the colloid inside the mixing box 200, the colloid seeps out along multiple discharge ports 306 and falls into the discharge hopper 308, so that the operator can collect the mixed colloid.

[0026] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, an arc-shaped plate 211 is fixedly connected to the bottom outer wall of the partition 212, and an inclined plate 307 is fixedly connected to the inner wall of the mixing box 200. The inclined plate 307 is located below the arc-shaped plate 211. When the colloid falls from the cavity inside the mixing box 200, it is guided by the arc-shaped plate 211 and the inclined plate 307 to prevent the colloid from sticking to the bottom inner wall of the mixing box 200 when it falls.

[0027] like Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the sealing structure 4 includes a bottom plate 401 fixedly connected to the inner wall of the mixing tank 200. The bottom plate 401 is annular. One outer wall of the bottom plate 401 is fixedly connected to the inner wall of the mixing tank 200. The outer wall of the bottom plate 401 away from the inner wall of the mixing tank 200 is fixedly connected to the bottom outer wall of the inclined plate 307. A fixing block 403 is fixedly connected to the top of the bottom plate 401. Several fixing blocks 403 are provided. Taking one fixing block 403 as an example, the fixing block 403 is located on the top of the bottom plate 401 near the inner wall of the mixing tank 200. A cylinder 404 is rotatably connected to the outer wall of the fixing block 403. A first connecting rod 405 is rotatably connected to the telescopic end of the cylinder 404. The end of the first connecting rod 405 away from the cylinder 404 is rotatably connected to the top of the bottom plate 401. Next, the rotatable connection point between the first connecting rod 405 and the base plate 401 is located at the top center of the base plate 401. The end of the first connecting rod 405 near the cylinder 404 is rotatably connected to the second connecting rod 406. The end of the second connecting rod 406 away from the first connecting rod 405 is rotatably connected to the top plate 402. The top of the fixing block 403 abuts against the bottom of the top plate 402. The side of the top plate 402 away from the mixing box 200 is in contact with the outer wall of the inclined plate 307. The outer wall of the top plate 402 near the inclined plate 307 is provided with an inclined angle. The fixing block 403 provides initial support for the top plate 402. The support assembly composed of the cylinder 404, the first connecting rod 405, and the second connecting rod 406 also supports the top plate 402 to prevent the top plate 402 from tilting during placement. In use, several cylinders 404 are activated. Taking one cylinder as an example, after activating cylinder 404, the telescopic end of cylinder 404 pushes the end of first connecting rod 405 away from the base plate 401 to move away from the fixed block 403. Simultaneously, the horizontal height of the end of first connecting rod 405 away from the base plate 401 is raised. At this time, first connecting rod 405 drives the end of second connecting rod 406 away from the top plate 402 to move synchronously. With the cooperation of first connecting rod 405 and second connecting rod 406, the top plate 402 is raised. During the lifting process, since the radial dimension of the top plate 402 does not change and the inclined plate 307 is set in an inverted cone shape, the outer wall of the inclined plate 307 will gradually shrink as the top plate 402 is lifted. When the outer wall of the inclined plate 307 is in contact with the bottom of the arc plate 211, the inclined plate 307 seals the gap between the arc plate 211 and the mixing box 200, so as to prevent the colloid from falling along the inclined arc plate 211 due to gravity when the mixing is incomplete, thereby avoiding the occurrence of insufficient mixing of some colloids during the mixing process.

[0028] like Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, a return spring 407 is fixedly connected to the top of the base plate 401. The number and position of the return springs 407 are respectively matched with the number and position of the cylinders 404. Taking one of the return springs 407 as an example, the end of the return spring 407 away from the base plate 401 is fixedly connected to the top plate 402. A support rod 408 is fixedly connected to the top of the base plate 401. A slot is opened through the outer side wall of the support rod 408. An extension rod 409 is slidably connected to the inner side wall of the support rod 408. A protrusion is provided on the outer side wall of the end of the extension rod 409 inside the support rod 408. The outer side wall of the protrusion fits with the inner side wall of the slot. The end of the extension rod 409 away from the support rod 408 is fixedly connected to the bottom of the top plate 402. The return spring 407 is located outside the support rod 408 and the extension rod 409. When in use, when the top plate 402 is raised, the extension rod 409 is raised along the slot opened on the outer wall of the support rod 408, and the support rod 408 and the extension rod 409 restrict the lifting direction of the top plate 402 to prevent the top plate 402 from shifting its angle during lifting, thereby preventing the top plate 402 from damaging the inclined plate 307.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
